Serrapeptase: Why the Empty Stomach Rule Exists

Serrapeptase is commonly formulated for between-meal use. Here is the reasoning behind delayed release and empty-stomach label directions, and where the evidence remains limited.

Serratiopeptidase is a proteolytic enzyme, it breaks down protein. Because it is a protein-digesting enzyme, how and when it is taken relative to food is part of how it is commonly formulated and labeled.

Why timing is part of the label directions

Taken with a meal, serrapeptase has protein from that meal available to act on. That is part of the reasoning behind label directions that recommend taking it between meals, on an empty stomach, rather than with food.

Delayed release is the other half

Stomach acid can break down enzymes before they move further through the digestive tract. Delayed-release capsules are designed to help protect the enzyme from the stomach environment before it reaches the small intestine. Serrapeptase is commonly formulated for use between meals rather than with food. Delayed-release capsules are intended to help protect the enzyme from the stomach environment. However, evidence about oral absorption, systemic activity and long-term clinical effects remains limited.

What we do not claim

We do not claim that oral serrapeptase reliably reaches circulation intact, and we do not make claims about inflammation resolution or respiratory comfort. AvalonX Serrapeptase 125 is formulated as a delayed-release capsule intended for empty-stomach use, consistent with common label conventions for this enzyme, while the underlying research base continues to develop.

All the good stuff. No noise.
